Well, it doesn't end with China. Around ~2010, once you scrub off the weasel word hedging, The Economist was predicting an imminent Eurozone breakup. It didn't predict the entirely predictable austerity recessions of 2012-2015. They were fairly bullish on Abenomics in Japan. They were very bullish on the future of BRICS around ~2008, out of which Brazil, Russia and South Africa are stagnating ever since.

Then, there's a very important tool in forming editorial slant - omitting reporting on inconvenient facts. Italy and Spain, the putatively sluggish laggards strangled by overly strict labor protection laws, have somehow overtaken the allegedly dynamic UK in labor productivity. Ireland, the purported economic wonder, have a household disposable income (a fairly good metric of material standards of living), lower than Italy and much lower than France. We keep hearing about the importance of education, competitiveness, R&D and ease of doing business, yet somehow Finland, which tops the rankings, is in year 14 of it's economic stagnation. Have you heard any of this from The Economist?
